bossanovalithium writes: Hydro-fracking involves shooting incredibly high-pressure "fluids" into oil and methane gas deposits to fracture the rock around it and release the gas. The Big Energy folks point out how economically important fracking is for the United States.

What's really important to focus on is that word "fluids". The people doing the fracking don't like to talk about what those fluids contain. They even have the law on their side in keeping it secret. The "Halliburton Loophole" is an artifact of the Bush Administration. It stops the EPA from regulating the chemicals added to water used for fracking.
